The dynamic behaviour of a real homogeneous earth dam overlaying a stiff natural clayey deposit and subjected to seismic loading has been studied using a fully coupled effective stress approach implemented in a non commercial finite element code. The mechanical behaviour of the different soils involved in the problem is simulated in the analyses using a recently developed multisurface elasto-plastic model. Its calibration is based on the available experimental data relative to the materials of the embankment and of the foundation layer. In order to define the initial stress state and the values of the model internal variables, a simplified geological history of the deposit, the dam construction stages and the reservoir impounding are simulated before the application of the earthquake at the bedrock level. A critical review of the role of the assumed constitutive hypothesis, of the hysteretic damping introduced by the model and the viscous damping artificially added in the analyses is addressed and some general conclusions are proposed in the final part of the paper.
